Hi George,
I believe I'm pretty much on top of that development, please see:
http://www.gyges.dk/Wilde%20&%20Zahme%20Sau.htm
My surprise is more related to the total lack of mention of Zahme Sau in the period mentioned. Let me also add. Iaw the KTB from August 1943 the twin engined fighter fly both Wilde Sau and Zahme Sau for a total of 702 sorties claiming 182 kills. Then suddenly there is no mention of Zahme Sau (except for less than 10 sorties) for 3 month. I think it is more of a question of terminology, than a reflection of the actual concept of employment, or a drunk, sloppy and frustrated KTB Führer.
Ref BAMA RL 8/91.
